Recent studies showed that absence of Fermi velocity at certain magic angles in twisted bilayer graphene (TBG) results in unconventional superconductivity [1]}, [2]} at low temperatures. The theoretically predicted flat bands near magic angles [3]}, [4]} contribute to superconducting states depending on the carrier density and twist angle. These remarkably flat bands with strongly correlated states also exhibit Mott-like insulator behavior at half-filling of the moiré subbands. The flat bands indicate van Hove singularities in the carrier DOS near the Fermi level [5]}, which, if coupled with good carrier conductivity, is highly desirable for thermoelectric applications. This combination of features in the DOS, in addition to the secondary bandgap between the lowest and second subbands in TBG, creates a narrow transport distribution function (TDF) [6]}. Then states bunched around sharp features in the DOS translate into improved Seebeck coefficient and maximize the PF[7]}, [8]}. The highly tunable band structure of TBG offers a new lever of control and a novel avenue to further decouple Seebeck and conductivity to achieve unprecedented PFs. However, little is yet known about the TE performance of TBG and its dependence on twist angle except at very low temperatures [9]}.
